    \[(x-8)^{2}-1 = x^2-16x+64-1=x^{2}-16x+63 = 0\]

    Solve for \( \large x^{2}-16x+63 = 0\)

    same as above but I applied the difference of 2 squares to make it faster

    ok so with the the equation so with the equation f(x)=2x^2-12 i would do the same thng right

    12 is not a perfect square

    to solve for x yes make the function = 0
